Udvidelse af Perl med C, en introduktion/Expanding Perl with C, an introduction (Dennis Haney)

60 minutes, Intermediate, in English

Dette er en introduktion til hvordan man kan bruge C biblioteker og funktioner under Perl. Perl benytter XS for at lime disse to programmeringssprog sammen. XS er et sprog der minder lidt om C, men pŒ grund af dets høje kompleksitet benyttes oftest modulet Inline::C i stedet, da denne automatisk kan håndtere mange af besværlighederne. Dermed skal programmøren "kun" lære Perl's interne API. Der vil blive lagt kraftig vægt på eksempler, og der vil blive gennemgået følgende:

This will be an introduction on how to use C libraries and functions inside Perl. Perl uses XS to glue the two programming languages together. XS is a language which resembles C a bit, but due to its high complexity the module Inline::C is often used instead, since that is capable of handling much of the difficulty. Then the programmer "only" have to learn Perl's internal API.

The talk will make full use of examples and the following subjects will be touched:

• A simple introduction to Perl internal types
• Making function calls to simple C functions
• Returning simple data to Perl
• Handling allocation of data in Perl
• Handling Perl-style arrays and hashes
• Usage of Perl's variables
• Calling Perl code from C
• Simple objects in C
